BACKGROUND
The present disclosure relates generally to information handling systems, and more particularly to a testing system for networking information handling systems.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Some information handling systems such as, for example, networking devices, may undergo a variety of performance and quality testing. For example, switch devices may be subject to “snake” tests that are used to analyze and ensure the stability of the switch device with regards to load capabilities, throughput capabilities, latency, RFC 2544 performance, and/or other switch device characteristics. In order to perform snake testing on a switch device having, for example, 48 testing ports, a user must prepare the switch device such that each pairs of ports between the 1st port and the 48th port are connected via a respective cable (e.g., a 2nd port and a 3rd port must be connected by a 1st cable, a 4th port and a 5th port must be connected by a 2nd cable, and so on up to a 46th port and 47th port being connected by a 23rd cable). The 1st port and the 48th port are then connected via respective cables to a load generator device, and the load generator device may be operated to send traffic to the 1st port such that it is routed by the switch device through all of the cabled ports and received back from the 48th port. The load generator device may also be operated to send traffic to the 48th port such that it is routed by the switch device through all of the cabled ports and received back from the 1st port. These bi-directional traffic flows may then be analyzed to determine the switch characteristics described above. The preparation of the switch device with the cabling, and the removal of the cabling from the switch device, is a time consuming process that can be subject to error and that typically takes much longer than the actual testing itself.
Accordingly, it would be desirable to provide an improved testing system for networking devices.

While specific networking devices have been illustrated and described, one of skill in the art in possession of the present disclosure will recognize that a wide variety of modification to the networking devices illustrated and described herein (e.g., more or fewer networking device connectors, other components that provide other functionality of the networking device, etc.) will fall within the scope of the present disclosure.
Referring now to
FIGS. 4A, 4B, 4C, 4D, and 4E, an embodiment of a
testing device 400 is illustrated. As discussed further below,
FIGS. 4A-4E illustrate a specific example of a

402 having a
top surface 402 a, a
bottom surface 402 b located opposite the base
402 from the
top surface 402 a, a

front surface 402 d located opposite the base
402 from the
rear surface 402 c and extending between the
top surface 402 a and the
bottom surface 402 b, and a pair of sides surfaces
402 e and
402 f that are located opposite the base
402 from each other and that extend between the
top surface 402 a, the

406 b are substantially the same (e.g., Registered Jack-45 (RJ-45) female connectors or other networking device connectors known in the art), but in other embodiments may include some connectors that are different than other connectors while remaining within the scope of the present disclosure.
The
testing device 400 also includes a networking device securing subsystem that, in the illustrated embodiment, is provided on the
base 402 and includes securing
members 408 that are located adjacent respective first testing device connectors, and one or more securing
member actuators 410 that are configured to engage and disengage the securing
members 408 to allow the securing
members 408 to couple to and decouple from a networking device, as discussed in further detail below.
FIG. 4C illustrates a specific embodiment of the networking device securing subsystem, with the securing
members 408 located adjacent respective first testing device connectors and extending into the base
402 such that the securing
member actuators 410 may engage at least a portion of the securing
members 408. For example, the securing
members 408 may be provided by conventional securing tabs on an RJ-45 male connector that extend into the
base 402 and that are configured to engage an RJ-45 female connector (e.g., on the networking device
200) to secure the RJ-45 male connector in the RJ-45 female connector, and the securing member actuator(s)
410 may be moveable relative to the base
402 in order to engage the securing
members 408 to disengage them from the RJ-45 female connector to allow the RJ-45 male connector to be removed from the RJ-45 female connector. In some embodiments, the securing
members 408 may only be provided adjacent particular first
testing device connectors 404 c, with no securing members (e.g., no RJ-45 male connector securing tabs) provided adjacent the remaining first testing device connectors, as illustrated. However, while a specific example of a networking device securing subsystem is illustrated and described in
FIG. 4C, one of skill in the art in possession of the present disclosure will recognize that a wide variety of different components and configurations may be used to provide a networking device securing subsystem that will enable the functionality discussed below and thus fall within the scope of the present disclosure.
Referring now to
FIGS. 4C, 4D, and 4E, an internal view of the
base 402 of the
testing device 400 is illustrated to provide an example of the connections between the first
testing devices connectors 404 a and
404 b and the second
testing device connectors 406 a and
406 b, as well as the connections between the first
testing device connectors 404 c. As illustrated in the embodiment of
FIG. 4C, the first
testing device connector 404 a may be connected to the second
testing device connector 406 a by an
interconnect 412 that is configured to transmit data traffic between the first
testing device connector 404 a and the second
testing device connector 406 a as discussed below. Similarly, as illustrated in the embodiment of
FIG. 4D, the first
testing device connector 404 b may be connected to the second
testing device connector 406 b by an
interconnect 414 that is configured to transmit data traffic between the first
testing device connector 404 b and the second
testing device connector 406 b as discussed below. While the
interconnects 412 and
414 are illustrated as physical interconnects (e.g., cabling, wiring, traces on a circuit board, etc.), the functionality of transmitting signals between first testing device connectors and second testing device discussed below may be provided in a variety of manners including, for example, configuring the
testing device 400 to provide a “pass-through” connection, defining a channel in the
base 402 of the
testing device 400 that allows a cabled (or other) connector to extend through the base
402 to engage a networking device connector on the
networking device 200, and/or configuring the
testing device 400 in other manners that would be apparent to one of skill in the art in possession of the present disclosure.
As illustrated in
FIG. 4E, pairs of the first
testing device connectors 404 c may be connected together by
respective interconnects 416 that are configured to direct data traffic between the first
testing device connector 404 c as discussed below. Similarly as discussed above with the first
testing devices connectors 404 a and
404 b and the second
testing device connectors 406 a and
406 b, the first
testing device connectors 404 c may be connected together by cabling or wiring provided between the connectors. However, in other embodiments, a circuit board may be provided in the
testing device 400, with the first
testing device connectors 404 c mounted to that circuit board, and traces on the circuit board providing the
interconnects 416 between those first
testing device connectors 404 c. Similarly, the first
testing devices connectors 404 a and
404 b and the second
testing device connectors 406 a and
406 b may be mounted to that circuit board and connected via traces while remaining within the scope of the present disclosure. However, while specific examples of the
testing device 400 have been illustrated and described, one of skill in the art will recognize that a wide variety of modification to the
testing device 400 illustrated in
FIGS. 4A-4E may be made while still providing the functionality and benefits discussed below, and thus will fall within the scope of the present disclosure.
For example, with reference to
FIGS. 5A and 5B, an embodiment of a
testing device 500 is illustrated with 8 testing device connectors (i.e., an “8 connector testing device”), and one of skill in the art in possession of the present disclosure will recognize that the
testing device 500 may be used with the
testing device 400 of
FIGS. 4A-4E in a specific embodiment to perform the testing discussed below on a networking device with 32 networking device connectors. Furthermore, the
testing device 500 is just one example of a testing device with a particular number of connectors that allow for combinations of the testing devices of the present disclosure to be used as discussed below. In the illustrated embodiment, the
testing device 500 includes a base
502 having a
top surface 502 a, a
bottom surface 502 b located opposite the base
502 from the
top surface 502 a, a
front surface 502 c extending between the
top surface 502 a and the
bottom surface 502 b, a
rear surface 502 d located opposite the base
502 from the
front surface 502 c and extending between the
top surface 502 a and the
bottom surface 502 b, and a pair of sides surfaces
502 e and
502 f that are located opposite the base
502 from each other and that extend between the
top surface 502 a, the
bottom surface 502 b, the
front surface 502 c, and the
rear surface 502 d.
A plurality of first testing device connectors are provided on and/or accessible via the
front surface 502 c, and are designated the first
testing device connector 504 a, the first
testing device connector 504 b, and the remaining first
testing device connectors 504 c, each of which may be used similarly as the corresponding first
testing device connector 404 a, first
testing device connector 404 b, and first
testing device connectors 404 c on the
testing device 400 in the manner described below. In the illustrated embodiment, each of the first
testing device connectors 504 a,
504 b, and
504 c are substantially the same (e.g., Registered Jack-45 (RJ-45) male connectors or other networking device connectors known in the art) and extend from the
front surface 502 a of the
base 502, but in other embodiments may include some connectors that are different than other connectors while remaining within the scope of the present disclosure. A plurality of second testing device connectors are provided on and/or accessible via the
rear surface 502 d, and are designated the second
testing device connector 506 a and the second
testing device connector 506 b, each of which may be used similarly to the corresponding second
testing device connector 506 a and second
testing device connector 506 b on the
testing device 400 in the manner described below. In the illustrated embodiment, each of the second
testing device connectors 506 a and
506 b are substantially the same (e.g., Registered Jack-45 (RJ-45) female connectors or other networking device connectors known in the art), but in other embodiments may include some connectors that are different than other connectors while remaining within the scope of the present disclosure.
The
testing device 500 also includes a networking device securing subsystem that, in the illustrated embodiment, is provided on the
base 502 and includes securing
members 508 that are located adjacent respective first testing device connectors, and one or more securing
member actuators 510 that are configured to engage and disengage the securing
members 508 to allow the securing
members 508 to couple to a networking device, similarly as discussed in further detail below with regard to the networking device securing subsystem on the
testing device 400. While not explicitly illustrated, the networking device securing subsystem on the
testing device 500 may operate similarly to the networking device securing subsystem on the
testing device 400 as described with reference to
FIG. 4C above. Furthermore, while no internal view of the
testing device 500 is provided, connections between the first
testing devices connectors 504 a and
504 b and the second
testing device connectors 506 a and
506 b, as well as connections between the first
testing device connectors 504 c, may be provided in the
testing device 500 in substantially the same manner as described for the
testing device 400 with reference to
FIGS. 4C, 4D and 4E above. One of skill in the art in possession of the present disclosure will recognize how the
testing device 500 illustrated in
FIG. 5 is but one of a variety of different testing devices that may be provided according to the teachings of the present disclosure in order to allow the network device testing discussed below to be performed on any of a variety of different networking devices having different numbers of networking device connectors.
In another example, with reference to
FIG. 6, an embodiment of a
testing device 600 is illustrated that is substantially similar to the
testing device 400 of
FIGS. 4A-4E, but with a modified network device securing subsystem. As such, components of the
testing device 600 that are similar to the
testing device 400 have provided with the same reference numbers. The networking device securing subsystem of the
testing device 600 is provided on the
base 402 and includes securing
members 408 that are located adjacent respective first
testing device connectors 404 c, securing
members 602 that are located adjacent respective first
testing device connectors 404 c, and one or more securing
member actuators 410 that are configured to engage and disengage the securing
members 408 and
602 to allow the securing
members 408 and
602 to couple to a networking device, similarly as discussed in further detail below with regard to the network device securing subsystem on the
testing device 400. While not explicitly illustrated, the networking device securing subsystem on the
testing device 600 may operate similarly to the networking device securing subsystem on the
testing device 400 as described with reference to
FIG. 4C above, with the exception that additional securing members (i.e., the securing members
602) are used to secure the
testing device 600 the
networking device 200, and the securing
member actuators 410 are configured to cause the securing
members 408 and
602 to disengage the
networking device 200. One of skill in the art in possession of the present disclosure will recognize how the
testing device 600 illustrated in
FIG. 6 is but one of a variety of different testing devices that may be provided according to the teachings of the present disclosure in order to allow the testing devices discussed below to be secured to a networking device (e.g., by any number of securing members located anywhere on the testing device and configured to be disengaged from any portion of the networking device by securing member actuators).
Referring now to
FIG. 7, an embodiment of a
method 700 for testing a networking device is illustrated. As discussed below, one or more testing devices may be provided according to the teachings of the present disclosure, and connected to a networking device that is to undergo testing. A load generator device may then be coupled to the testing device(s) and used to generate traffic that is provided through a testing device to the networking device. The networking device and the testing device(s) may then cooperate to route that data traffic through pairs of connectors on the testing device(s) such that the data traffic travels through each of the networking device connectors on the networking device, out of a final networking device connector on the networking device, and through a testing device to the load generator. The data traffic received at the load generator may then be compared to the data traffic provided by the load generator in order to test various characteristics of the networking device. One of skill in the art in possession of the present disclosure will recognize that the testing device(s) of the present disclosure provide for quick, efficient, and accurate setup and removal of the networking device testing system that overcomes the problems associated with conventional cabling that is used to provide conventional networking device testing systems.
The
method 700 begins at
block 702 where testing device(s) are coupled to a networking device and a load generator device. In the embodiment illustrated and described below, a pair of 24 connector testing devices are coupled to a 48 connector networking device, each other, and a load generator device in order to provide a networking device testing system. However, as discussed above, a single testing device, testing devices having different numbers of connectors, or different numbers of testing devices may be utilized to provide networking device testing systems for networking devices having any number of connectors (e.g., a 32 connector networking device may be testing using a 32 connector testing device, two 16 connector testing devices, one 16 connector testing device and two 8 connector testing devices, etc.) As such, it should be appreciated that networking device testing systems may be provided with sets of testing devices having different numbers of connectors that allow the testing of any of a variety of networking devices. For example, given the similarities of horizontal and vertical spacing between networking device connectors on a vast majority of the networking device currently available in the networking device market, the inventors of the subject matter of the present disclosure have found that approximately 10 different testing device configurations would cover 90% of the current networking device testing system market for currently available networking devices.
Referring to
FIG. 8, and with reference to
FIGS. 2 and 4A-4E, a first stage networking device
testing system setup 800 is illustrated in which a first
802 of the
testing devices 400 is connected to the
networking device 200. For example, a user may position the first
802 of the
testing devices 400 adjacent the
networking device 200 such that its
rear surface 402 c is facing the
chassis 202 of the
networking device 200 with the first
testing device connector 404 a aligned with the
networking device connector 204 a, the first
testing device connector 404 b aligned with the
networking device connector 204 b, and the remaining first
testing device connectors 404 c aligned with respective
networking device connectors 204 c. The user may then move the first
802 of the
testing devices 400 towards the
networking device 200 such that the first
testing device connector 404 a engages the
networking device connector 204 a, the first
testing device connector 404 b engages the
networking device connector 204 b, and the remaining first
testing device connectors 404 c engage respective
networking device connectors 204 c. In addition, movement of the first
802 of the
testing devices 400 towards the
networking device 200 to engage the first testing device connectors and respective networking device connectors as discussed above causes the securing
members 408 on its networking device securing subsystem to engage the
networking device 200 to secure the first
802 of the
testing devices 400 to the
networking device 200, as illustrated in
FIG. 8. While the securing
members 408 are illustrated and described as being provided by conventional securing tabs on RJ-45 male connectors (i.e., the first
testing device connectors 404 c) that engage RJ-45 female connectors (i.e., the
networking device connectors 204 c) to secure their RJ-45 male connector in the RJ-45 female connectors, one of skill in the art will recognize that other types of securing members may be provided anywhere on the
testing devices 400 and coupled to the
networking device 200 in other manners (e.g., by engaging subsystems anywhere on the
chassis 202 of the networking device
200) to secure the first testing device connectors in the networking device connectors while remaining within the scope of the present disclosure.
Referring to
FIG. 9, and with reference to
FIGS. 2 and 4A-4E, a second stage networking device
testing system setup 900 is illustrated in which a second
902 of the
testing devices 400 is connected to the
networking device 200. For example, a user may position the second
902 of the
testing devices 400 adjacent the
networking device 200 such that its
rear surface 402 c is facing the
chassis 202 of the
networking device 200 with the first
testing device connector 404 a aligned with the
networking device connector 204 c, the first
testing device connector 404 b aligned with the
networking device connector 204 d, and the remaining first
testing device connectors 404 c aligned with respective
networking device connectors 204 c. The user may then move the second
902 of the
testing devices 400 towards the
networking device 200 such that the first
testing device connector 404 a engages the
networking device connector 204 c, the first
testing device connector 404 b engages the
networking device connector 204 d, and the remaining first
testing device connectors 404 c engage respective
networking device connectors 204 c. In addition, movement of the second
902 of the
testing devices 400 towards the
networking device 200 to engage the first testing device connectors and respective networking device connectors as discussed above causes the securing
members 408 on its networking device securing subsystem to engage the
networking device 200 to secure the second
902 of the
testing devices 400 to the
networking device 200, substantially as described above and as illustrated in
FIG. 9.
Referring now to
FIG. 10, an embodiment of a networking
device testing system 1000 is illustrated that is provided following the first stage networking device
testing system setup 800 and the second stage networking device
testing system setup 900 illustrated in
FIGS. 8 and 9. In an embodiment, following the coupling of the first
802 and the second
902 of the
testing devices 400 to the
networking device 200 as discussed above, the user may couple a
load generator device 1002 to the first
802 and the second
902 of the
testing devices 400. For example, the user may couple a cable
1004 (e.g., an Ethernet cable) between the
load generator device 1002 and the first
802 of the
testing devices 400 by connecting a
connector 1004 a (e.g., an RJ-45 male connector) on the
cable 1004 to the second
testing device connector 406 a on the first
802 of the
testing devices 400, and connecting another connector (not illustrated) on that
cable 1004 to the
load generator device 1002, as illustrated in
FIG. 10. Similarly, the user may couple a cable
1006 (e.g., an Ethernet cable) between the
load generator device 1002 and the second
902 of the
testing devices 400 by connecting a
connector 1006 a (e.g., an RJ-45 male connector) on the
cable 1006 to the second
testing device connector 404 b on the second
902 of the
testing devices 400, and connecting another connector (not illustrated) on that
cable 1006 to the
load generator device 1002, as illustrated in
FIG. 10. In an embodiment, the
load generator device 1002 may be a load generator device available from IXIA® of Calabasas, Calif., United States, a load generator device available from SPIRENT® Communications of Crawley, West Sussex, United Kingdom; a load generator device utilizing LOADRUNNER® available from HEWLETT-PACKARD® Company of Palo Alto, Calif., United States; and/or a variety of other load generator devices known in the art that are configured to provide the functionality discussed below.
Furthermore, the user may couple the first
802 of the
testing devices 400 to the second
902 of the
testing devices 400. For example, the user may couple a cable
1008 (e.g., an Ethernet cable) between the first
802 of the
testing devices 400 and the second
902 of the
testing devices 400 by connecting a
connector 1008 a (e.g., an RJ-45 male connector) on the
cable 1008 to the second
testing device connector 406 b on the first
802 of the
testing devices 400, and connecting a
connector 1008 b (e.g., an RJ-45 male connector) on the
cable 1008 to the second
testing device connector 406 a on the second
902 of the
testing devices 400, as illustrated in
FIG. 10. With the first
802 and the second
902 of the
testing devices 400 coupled to each other and the
load generator device 1002, a networking
device testing system 1000 is provided for testing a 48 connector networking device using two 24 connector testing devices. However, one of skill in the art in possession of the present disclosure will recognize that the setup of the networking device testing system may be modified when different testing devices and/or networking devices are used. For example, if a single testing device is used (e.g., a 48 connector testing device, the illustrated 24 connector testing device on a 24 connector networking device, etc.), the
load generator 1002 may be connected via cabling directly to each of the second
testing device connector 406 a and
406 b on that testing device. Furthermore, if more than two
testing devices 400 are used (e.g., three 16 connector testing devices, the illustrated 24 connector testing device and two 12 connector testing devices, etc.), those testing
devices 400 may be coupled together by cabling that is similar to the
cable 1008 in a substantially similar manner as discussed above.
The
method 700 then proceeds to block
704 where a testing device receives data traffic from the load generator device through a second testing device connector. Referring back to
FIG. 10, and with reference to
FIGS. 2, 3, and 4A-4E, in an embodiment of
block 704, the first
802 of the
testing devices 400 receives data traffic from the
load generator device 1002 through its second
testing device connector 406 a. For example, the
load generator device 1002 may generate first data traffic having first data traffic characteristics, and provide that first data traffic through the
cable 1004 and the
connector 1004 a to the second
testing device connector 406 a on the first
802 of the
testing devices 400. As discussed in further detail below, embodiments in which initial data traffic is provisioned at
block 704 by the
load generator device 1002 to the first
802 of the
testing devices 400 via its second
testing device connector 406 a may be performed to test traffic flow through the
networking device 200 in a first direction.
In another embodiment of
block 704, the second
802 of the
testing devices 400 receives data traffic from the
load generator device 1002 through its second
testing device connector 406 b. For example, the
load generator device 1002 may generate first data traffic having first data traffic characteristics, and provide that first data traffic through the
cable 1006 and the
connector 1006 a to the second
testing device connector 406 b on the second
902 of the
testing devices 400. As discussed in further detail below, embodiments in which initial data traffic is provisioned at
block 704 by the
load generator device 1002 to the second
802 of the
testing devices 400 via its second
testing device connector 406 b may be performed to test traffic flow through the
networking device 200 in a second direction that is opposite the first direction discussed above. One of skill in the art in possession of the present disclosure will recognize that a networking device test may involve performing blocks
702-
712 of the
method 700 multiple times to provide bi-direction data traffic (e.g., data traffic in each of the first direction and the second direction) through the
networking device 200.
The
method 700 then proceeds to block
706 where the testing device directs data traffic though a first testing device connector to the networking device. In an embodiment of
block 706 in which data traffic is being provided through the
networking device 200 in the first direction, discussed above, the first
802 of the
testing devices 400 directs the data traffic received from the
load generator device 1002 at
block 704 through its first
testing device connector 404 a to the
networking device 200. For example, data traffic received at the second
testing device connector 406 a on the first
802 of the
testing devices 400 may be directed through the
interconnect 412 to the first
testing device connector 404 a on the first
802 of the
testing devices 400, and then provided to the
networking device 200 via the connection of that first
testing device connector 404 a and the
networking device connector 204 a on the
networking device 200.
In an embodiment of
block 706 in which data traffic is being provided through the
networking device 200 in the second direction, discussed above, the second
802 of the
testing devices 400 directs the data traffic received from the
load generator device 1002 at
block 704 through its first
testing device connector 404 b to the
networking device 200. For example, data traffic received at the second
testing device connector 406 b on the second
802 of the
testing devices 400 may be directed through the
interconnect 414 to the first
testing device connector 404 b on the second
902 of the
testing devices 400, and provided to the
networking device 200 via the connection of that first
testing device connector 404 b and the
networking device connector 204 d on the
networking device 200.
The
method 700 then proceeds to block
708 where the testing device(s) cooperate with the networking device to route data traffic through pairs of the first testing device connectors. In embodiments of
block 708 in which data traffic is being provided through the networking device in the first direction, the
networking device 200 may operate to repeatedly direct data traffic that is received from the first
802 of the
testing devices 400 to
networking device connectors 204 e that are connected to the pairs of the first
testing device connectors 404 c on the first
802 of the
testing devices 400 that route that data traffic back to the
networking device 200 via the
interconnects 416. For example, with reference to
FIGS. 2, 3, and 4E, at
block 708 the data traffic received through the
networking device connector 204 a at
block 706 may be directed by the
testing engine 304 to the
networking device connector 204 e that is illustrated in
FIG. 2 as being positioned below the
networking device connector 204 a, which will result in that data traffic being provided to the first
802 of the
testing devices 400 through the connection of that
networking device connector 204 e and the first
testing device connector 404 c that is illustrated in
FIG. 4E as being positioned below the first
testing device connector 404 a. Furthermore, data traffic received by the first
802 of the
testing devices 400 through that first
testing device connector 404 c (i.e., the first
testing device connector 404 c that is illustrated in
FIG. 4E as being positioned below the first
testing device connector 404 a) is then directed via the
interconnect 416 back to the
networking device 200 through the connection of the first
testing device connector 404 c (which is illustrated in
FIG. 4E as being immediately adjacent and to the right of the first
testing device connector 404 a) and the
networking device connector 204 e (which is illustrated in
FIG. 2 as being immediately adjacent and to the right of the
networking device connector 204 a).
One of skill in the art in possession of the present disclosure will appreciate how the
testing engine 304 in the
networking device 200/
300 may then direct that data traffic back to respective ones of the first
testing device connectors 404 c on the first
802 of the
testing devices 400, and how the
interconnects 416 may direct that data traffic back to the
networking device 200/
300, such that the data traffic received by the
networking device 200 through the
networking device connector 204 a is routed through each of its
networking device connectors 204 e that are connected to respective first
testing device connectors 404 c on the first
802 of the
testing devices 400. For example, with reference to
FIGS. 2, 4E, and 10, this process at
block 708 routes the data traffic in a left-to-right direction (relative to the Figures), with the data traffic repeatedly ingressing the
networking device 200 via the
networking device connector 204 a and the top row of
networking device connectors 204 e that are located between the
networking device connectors 204 a and
204 c in
FIG. 2, and repeatedly egressing the
networking device 200 via the bottom row of
networking device connectors 204 e that are located to the left of the
networking device connector 204 b, as well as the
networking device connector 204 b, in
FIG. 2.
Data traffic egressing the
networking device 200 via the
networking device connector 204 b may be received at the first
testing device connector 404 b on the first
802 of the
testing devices 400 and directed through the
interconnect 414 to the second
testing device connector 406 b on the first
802 of the
testing devices 400. That data traffic may then be received through the
connector 1008 a and routed through the
cable 1008 via the
connector 1008 b to the second
902 of the
testing devices 400. The second
902 of the
testing devices 400 receives that data traffic through its second
testing device connector 406 a and provides it to the
networking device 200. For example, data traffic received at the second
testing device connector 406 a on the second
902 of the
testing devices 400 may be directed through the
interconnect 412 to the first
testing device connector 404 a on the second
902 of the
testing devices 400, and provided to the
networking device 200 via the connection of that first
testing device connector 404 a and the
networking device connector 204 c on the
networking device 200.
Similarly as discussed above, the
networking device 200 may operate to repeatedly direct data traffic that is received from the second
902 of the
testing devices 400 to
networking device connectors 204 e that are connected to the pairs of the first
testing device connectors 404 c on the second
902 of the
testing devices 400 that route that data traffic back to the
networking device 200 via the
interconnects 416. For example, with reference to
FIGS. 2, 3, and 4E, at
block 708 the data traffic received through the
networking device connector 204 c at
block 706 may be directed by the
testing engine 304 to the
networking device connector 204 e that is illustrated in
FIG. 2 as being positioned below the
networking device connector 204 c, which will result in that data traffic being provided to the second
902 of the
testing devices 400 through the connection of that
networking device connector 204 e and the first
testing device connector 404 c that is illustrated in
FIG. 4E as being positioned below the first
testing device connector 404 a. Furthermore, data traffic received by the second
902 of the
testing devices 400 through that first
testing device connector 404 c (i.e., the first
testing device connector 404 c that is illustrated in
FIG. 4E as being positioned below the first
testing device connector 404 a) is then directed via the
interconnect 416 back to the
networking device 200 through the connection of the first
testing device connector 404 c (which is illustrated in
FIG. 4E as being immediately adjacent and to the right of the first
testing device connector 404 a) and the
networking device connector 204 e (which is illustrated in
FIG. 2 as being immediately adjacent and to the right of the
networking device connector 204 c).
One of skill in the art in possession of the present disclosure will appreciate how the
testing engine 304 in the
networking device 200/
300 may then direct that data traffic back to respective ones of the first
testing device connectors 404 c on the second
902 of the
testing devices 400, and how the
interconnects 416 may direct that data traffic back to the
networking device 200/
300, such that the data traffic received by the
networking device 200 through the
networking device connector 204 c is routed through each of its
networking device connectors 204 e that are connected to respective first
testing device connectors 404 c on the second
902 of the
testing devices 400. For example, with reference to
FIGS. 2, 4E, and 10, this process at
block 708 continues to route the data traffic in a left-to-right direction (relative to the Figures), with the data traffic repeatedly ingressing the
networking device 200 via the
networking device connectors 204 c and the top row of
networking device connectors 204 e that are located to the right of the
networking device connector 204 c in
FIG. 2, and repeatedly egressing the
networking device 200 via the bottom row of
networking device connectors 204 e that are located between the
networking device connectors 204 b and
204 d, as well as the
networking device connector 204 d, in
FIG. 2.
Without repeating substantially the same discussion detailed above for the first direction/left-to-right data traffic, one of skill in the art will appreciate that the second direction/right-to-left data traffic, which is provided when initial data traffic is provisioned at
block 704 by the
load generator device 1002 to the second
802 of the
testing devices 400 via its second
testing device connector 406 b, may be routed by the first
802 and the second
902 of the testing devices and the
networking device 200 in a similar manner. As such, in those embodiments and with reference to
FIGS. 2, 4E, and 10, data traffic may be routed in the right-to-left direction (relative to the Figures), with the data traffic repeatedly ingressing the
networking device 200 via the
networking device connector 204 d, the bottom row of
networking device connectors 204 e that are located between the
networking device connectors 204 b and
204 d, and the bottom row of
networking device connectors 204 e that are located to the left of the
networking device connectors 204 b in
FIG. 2, and repeatedly egressing the
networking device 200 via the top row of
networking device connectors 204 e that are located to the right of the
networking device connector 204 c, the top row of
networking device connectors 204 e that are located between the
networking device connector 204 a and
204 c, and the
networking device connector 204 a in
FIG. 2.
The
method 700 may then proceed to block
710 where a testing device provides data traffic to the load generator device through a second testing device connector. In an embodiment of
block 706 in which data traffic is being provided through the
networking device 200 in the first direction, the second
902 of the
testing devices 400 directs the data traffic received from the
networking device 200 at
block 708 to the
load generator device 1002. For example, data traffic received from the
networking device connector 204 d at the first
testing device connector 404 b on the second
902 of the
testing devices 400 may be directed through the
interconnect 414 to the second
testing device connector 406 b on the second
902 of the
testing devices 400, and provided to the
load generator device 1002 via the connection of that second
testing device connector 406 b, the
connector 1006 a on the
cable 1006, and through the
cable 1006 to the
load generator device 1002.
In another embodiment of
block 710 in which data traffic is being provided through the
networking device 200 in the second direction, the first
802 of the
testing devices 400 directs the data traffic received from the
networking device 200 at
block 708 to the
load generator device 1002. For example, data traffic received from the
networking device connector 204 a at the first
testing device connector 404 a on the first
802 of the
testing devices 400 may be directed through the
interconnect 412 to the second
testing device connector 406 a on the first
802 of the
testing devices 400, and provided to the
load generator device 1002 via the connection of that second
testing device connector 406 a, the
connector 1004 a on the
cable 1004, and through the
cable 1004 to the
load generator device 1002.
The
method 700 then proceeds to block
712 where the data traffic is analyzed. In an embodiment, the
load generator device 1002 may include a data traffic analysis subsystem that is configured to analyze the data traffic received from the
networking device 200/testing device(s)
400 at
block 710. In another embodiment, a data traffic analysis subsystem (e.g., e.g., an IHS) may be coupled to the
load generator device 1002 and configured to analyze the data traffic received from the
networking device 200/testing device(s)
400 at
block 710. In a specific embodiment, the analysis of the data traffic at
block 710 may include comparing the data received from the
networking device 200/testing device(s)
400 at
block 710 to the data traffic sent to the
networking device 200/testing device(s)
400 at
block 704 to determine whether any changes to that data traffic have occurred.
For example, as discussed above, at
block 704 the
load generator device 1002 may provide first data traffic having first data traffic characteristics to the
networking device 200/testing device(s)
400 and, at
block 710, the load generator device may receive back that same first data traffic with those same first data traffic characteristics. As such, the data traffic analysis subsystem may determine at
block 712 that no changes have occurred to the first data traffic or first data traffic characteristics during its transmission through the
networking device 200/testing device(s)
400, and thus the
networking device 200 may be considered to be operating properly. In another example, at
block 704 the
load generator device 1002 may provide the first data traffic having the first data traffic characteristics to the
networking device 200/testing device(s)
400 and, at
block 710, the load generator device may receive back second data traffic having second data traffic characteristics that is different than the first data traffic having the first data traffic characteristics. As such, the data traffic analysis subsystem may determine at
block 712 that changes have occurred to the first data traffic and/or first data traffic characteristics during its transmission through the
networking device 200/testing device(s)
400, and thus the
networking device 200 may be considered to be defective. While a specific example of a test/data traffic analysis has been provided, one of skill in the art in possession of the present disclosure will recognize that a variety of testing may be performed using the networking device testing system of the present disclosure, including load testing, throughput testing, latency testing, and/or other networking device testing known in the art.
Following the
method 700, the networking
device testing system 100 may be disassembled by disconnecting the
load generator device 1002 from the first
802 and second
902 of the
testing devices 400 via the disconnection of the
connectors 1004 a and
1006 a on the
cables 1004 and
1006, respectively, from the second
testing device connectors 406 a and
406 b, respectively, on the first
802 and second
902 of the
testing devices 400, respectively. Furthermore, the first
802 and second
902 of the
testing devices 400 may be disconnected from each other via the disconnection of the
connectors 1008 a and
1008 b on the
1008, from the second
testing device connectors 406 b and
406 a, respectively, on the first
802 and second
902 of the
testing devices 400, respectively. Each of the first
802 and second
902 of the
testing devices 400 may then be disconnected from the
networking device 200 by engaging the securing
member actuators 410 on that testing device
400 (e.g., by using the thumb and forefinger on each hand to move the securing
member actuators 410 on that
testing device 400 towards each other) to cause the securing
members 408 to disengage from the
networking device 200 so that that
testing device 400 may be moved away from the
networking device 200 to cause the first
testing device connectors 404 a,
404 b, and
404 c to disengage the networking device connectors on the
networking device 200.
Thus, systems and methods have been described that provide testing device(s) that provide for the setup and disassembly of a networking device testing system in a fraction of the time of conventional networking device testing systems (e.g., 20 to 30 minutes vs. less than a minute) while reducing the errors in networking device testing system setup that are associated with the time-consuming and inaccurate methods of separately cabling pairs of networking device connectors on the networking device. As discussed above, a single testing device may be configured to connect all of the networking device connectors on a networking device in order to perform testing, thus requiring simply connecting that testing device to the networking device and cabling that testing device with two cables to the load generator device. As also discussed above, combinations of testing devices may be utilized to connect all of the networking device connectors on a networking device in order to perform testing, thus requiring simply connecting those testing devices to the networking device, cabling pairs of those testing devices together with cable, and cabling two of those testing devices with two cables to the load generator device. One of skill in the art in possession of the present disclosure that has conducted conventional “snake” testing on a networking device will immediately recognize the improved setup accuracy and time savings that result from using testing devices according to the teachings herein.
Referring now to
FIG. 11A, an embodiment of a testing
device connector subsystem 1100 is illustrated. In the illustrated embodiment, a portion of a
testing device chassis 1102 is illustrated that may be provided on any of the testing device chassis discussed above (e.g., the
chassis 402 of
FIGS. 4A-4E) and that is configured to couple a single testing device connector (e.g., the first
testing device connectors 404 a,
404 b, and
404 c) to the
testing device chassis 1102. It should be understood that the structure illustrated in
FIG. 11B may be provided for a single testing device connector or any subset of the testing device connectors on the testing devices discussed above in order to allow those testing device connector(s) to be positioned on the testing device chassis in a configuration that matches the networking device connectors on a networking device that is to be tested.
A
connector coupling 1104 is provided in the
testing device chassis 1102 and is moveable in a
cavity 1105 defined by the testing device chassis
1102 (e.g., as indicated by the arrows extending from the connector coupling
1104), and may be connected or coupled to any of the
interconnects 412,
414, and/or
416 that are discussed above for coupling together testing device connectors on the
testing device 400. In the specific illustrated embodiment, the
connector coupling 1104 includes 8 contacts (e.g., for coupling to 8 contacts on a male RJ-45 connector), but may include any of a variety of electrical contact features to provide for a moveable electrical coupling between the testing device connector and the
interconnect 414,
414, and/or
416. A plurality of testing device connector positioning features
1106 are provided on the
testing device chassis 1102 and located about the perimeter of the
connector coupling 1104. In the illustrated embodiment, the testing device connector positioning features
1106 are illustrated as including
discrete locating elements 1106 a (i.e., the 9 circles illustrated on each testing device connector positioning feature
1106) and positioning channels
1006 b (i.e., the 12 lines illustrated on each testing device
connector positioning feature 1106 that connect the 9 circles), and as discussed below, testing device connectors may be provided with features that engage the testing device connector positioning features
1106 and that may be moved through the
positioning channels 1106 b to become seated in the locating
elements 1006 a to provide a desired position for that testing device connector on the
testing device chassis 1102. However, one of skill in the art in possession of the present disclosure will also recognize that the specific testing device connector positioning features
1106 illustrated in
FIG. 11A may be replaced by a variety of other moveable electrical couplings that may be provide connection, removal, and/or continuously/integrally adjustable positioning of the testing device connectors while remaining within the scope of the present disclosure.
Referring now to
FIG. 11B, a
testing device connector 1108 is illustrated coupled to the testing
device connector subsystem 1100, and may be any of the testing device connectors discussed above. The
testing device connector 1108 may include features (not illustrated) that are configured to engage respective ones of the testing device connector positioning features
1106 on the
testing device chassis 1102 to connect the
testing device connector 1008 to the
testing device chassis 1102 and, as discussed above, to allow the
testing device connector 1008 to move relative to the testing device chassis
1102 (e.g., via the positioning channels
1006 b on the testing device connector positioning features
1106) and be held in a desired position (e.g., via the locating
elements 1106 a on the testing device connector positioning features
1106). Furthermore, the
testing device connector 1108 may include one or more electrical contacts (e.g., 8 contacts on a male RJ-45 connector) that are configured to engage the
connector coupling 1004 while being moved into any of the configurable positions of the
testing device connector 1108 on the testing
device connector subsystem 1100, thus providing for the electrical connection of the
testing device connector 1108 to any of the
interconnects 412,
414, and
416 that are electrically connected to the
connector coupling 1104.
In a specific embodiment, the testing
device connector subsystem 1100 may be provided for each of the first
testing device connectors 404 a,
404 b, and
404 c on the
testing device 400, or combinations of the testing device connectors (e.g., subsets of 8 testing device connectors may be moveable relative to the
testing device chassis 1102 using features similar to those illustrated in
FIGS. 11A and 11B), and used to add testing device connectors, remove testing device connectors, and position testing device connectors on the
chassis 402 to configure the testing device connectors on the
testing device 400 for any networking device connector configuration on any networking device. Furthermore, the testing
device connector subsystem 1100 may provide for testing device connectors that “self-align” or “self-adjust” to the configuration of networking device connectors on a networking device. For example, a user may position a testing device adjacent a networking device such that the first testing device connectors discussed above are substantially aligned with the networking device connectors. Movement of the testing device towards the networking device will then cause the first testing device connectors to engage respective networking device connectors, while also moving relative to the testing device chassis via the
connector couplings 1106, to provide for self-alignment or self-adjustment of the first testing device connectors that changes the configuration of the first testing device connectors based on variations in the relative positioning of the networking device connectors. Thus, testing devices according to the teachings of the present disclosure may be configurable so that the number, positioning, types, and/or other characteristics of the testing device connectors may be selected by a user to conform to any networking device to be tested.
Although illustrative embodiments have been shown and described, a wide range of modification, change and substitution is contemplated in the foregoing disclosure and in some instances, some features of the embodiments may be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the embodiments disclosed herein.
